[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0024] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] The “first” and “second” involved in the present utility model do not represent specific quantities and orders, but are merely used to distinguish names.

[0027] Combined with Figure 1-5The adjustable occluder of the present embodiment comprises a conversion joint 1, provided with a cone head 2, the cone head 2 being a 15 mm cone head; a cap plug 3, cooperating with the cone head 2; a connecting cover 4, detachably connected to the cone head 2; a fixing tube 5, provided at one end of the connecting cover 4 away from the cone head 2, the fixing tube 5 being provided with a locking groove 6; a locking plug 7, provided in the fixing tube 5; a locking cover 8, detachably connected to the fixing tube 5 and pressing the locking plug 7; the conversion joint 1, The cone head 2, the connecting cover 4, the fixing tube 5, the locking groove 6, the locking plug 7 and the locking cover 8 are all annular structures and have a channel in the center to cooperate with the bronchial tube. The locking plug 7 is a rubber plug. The locking plug 7 has an interference fit with the bronchial tube. The bottom of the locking plug 7 is provided with a conical convex portion 9. The protrusion of the bottom center of the locking plug 7 is greater than the protrusion of the bottom edge of the locking plug 7. The bottom of the locking groove 6 is provided with a V-shaped guiding portion 10.

[0028] The adjustable occluder is provided with a locking plug 7 between the locking cover 8 and the fixing tube 5. When the locking cover 8 is screwed downward, the locking plug 7 is squeezed and deformed. The unique chamfered angle design on the locking plug can guide the locking plug 7 to deform inward, thereby fixing and sealing the catheter. The interference fit between the locking plug 7 and the bronchial catheter can prevent the conversion joint from sliding when it is not locked; the catheter fixing structure and the catheter can be completely removed from the cone head 2. If a problem occurs during use, the catheter can be re-inserted without removing the conversion joint 1 and the cap plug 3.

[0029] As a preferred solution of the utility model, a communicating positioning groove 11 and guide groove 12 are provided on the outer peripheral wall of the cone head 2, the guide groove 12 is open at one end close to the connecting cover 4, the positioning groove 11 is provided at the other end of the guide groove 12 and is circumferentially offset with the guide groove 12, and a limiting block 13 that slidably cooperates with the positioning groove 11 and the guide groove 12 is provided on the inner peripheral wall of the connecting cover 4. When the connecting cover 4 and the cone head 2 are connected, the limiting block 13 slides from the open end of the guide groove 12 to the other end, and then rotates a certain angle along the circumferential direction of the cone head 2 so that the limiting block 13 enters the positioning groove 11 to achieve axial limiting.

[0030] As a preferred solution of the utility model, a sealing gasket 14 abutting against the cone head 2 is provided in the connecting cover 4, and the sealing gasket 14 and the locking plug 7 are both silicone pads. The sealing gasket 14 is deformed by extrusion to achieve a sealing effect, and the elastic force generated by the extrusion of the sealing gasket 14 drives the connecting cover 4 to deviate in the direction away from the cone head 2, thereby making the limit block 13 abut against the inner wall of the positioning groove 11 to limit the axial displacement.

[0031] As a preferred solution of the present utility model, the locking cover 8 is connected to the fixing tube 5 via an anti-slip structure and a threaded structure.

[0032] As a preferred embodiment of the present invention, the locking cover 8 includes a locking pressure block 81 arranged in the fixed tube 5, and the anti-slip structure includes a first anti-slip ring 15 and a second anti-slip ring 16. The outer diameter of the first anti-slip ring 15 is greater than the inner diameter of the second anti-slip ring 16. The first anti-slip ring 15 is arranged on the outer peripheral wall of the locking pressure block 81, and the second anti-slip ring 16 is arranged on the inner peripheral wall of the fixed tube 5. The locking pressure block 81 is installed in the fixed tube 5 and the first anti-slip ring 15 passes over the second anti-slip ring 16 to realize the anti-slip function. The anti-slip structure is mainly used to realize the pre-connection of the locking cover 8 and the fixed tube 5.

[0033] As a preferred embodiment of the present invention, the locking cover 8 also includes an external connecting tube 82 sleeved on the outside of the fixed tube 5, the external connecting tube 82 is fixedly connected to one end of the locking pressure block 81, the threaded structure includes an internal thread 17 and an external thread 18, the internal thread 17 is arranged on the inner circumferential wall of the external connecting tube 82, and the external thread 18 is arranged on the outer circumferential wall of the fixed tube 5, when the locking cover 8 is threadedly tightened on the fixed tube 5, the locking pressure block 81 gradually presses the locking plug 7, thereby realizing the final fixation of the locking plug 7, and in order to facilitate the operation of the locking cover 8, an anti-slip structure is provided on the outer circumferential wall of the external connecting tube 82, and the anti-slip structure can be an anti-slip pattern or an anti-slip protrusion.

[0034] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
